It's only a no brainer if he gets to play again in the playoffs. Riding pine so Lovejoy and Cole can play is probably a bit frustrating. That said, I could see him being sold on signing a 1 year deal to rebound his career.
I'm still hesitant to move Pouliot. The guy is still young and I thought was playing some good hockey before he was benched. Plus we don't have much in the minors behind him while we have a few forwards. Expansion rules could change my mind though. As it stands, the most likely scenario is the Pens losing him or a goalie.
I love Nuke's skillset though so I'd probably pull the trigger.
Sheary-Crosby-Hornqvist
Wilson-Malkin-Nuke
Hagelin-Bones-Kessel
Kuhn-Cullen-Rust
Fehr
Maatta-Letang
Dumo-Daley
Cole-Schultz
depth dude
That looks really, really good. Then for expansion, you go the 7 F, 3 D route protecting Crosby, Malkin, Kessel, Hornqvist, Nuke, Hagelin, and whatever kid breaks out the most. Probably Sheary at this point.
